MATRIX.

Specification of Letters Patent.

Patented Oct. 20, 1914.

Application filed May 9, 1913. Serial N 0. 766,484.

To all whom it may concern:

lie it known that I, CLAUDE L. FRIEL, a citizen'of the United States,residing at the city of Los Angeles, in the county of Los .-\ngeles andState of California, have-invented new and useful Improvements inlaiatriccs, of which the following is'a specification.

"My invention relates to olygonal matrices having four or more castingedges in which edges molds to form characters of forms are located whichare used in line casting, and the object thereof is to provide matricesthat are susceptible of being distributed into magazines so that theywill occupy the same position in the magazine as before each usethereof. I accomplish this object by the matrix described herein andillustrated in the accompanying drawings forming a part of thisapplication in which:

Figure l is a front elevation of my improved matrix. Fig. 2 is a topedge view. Fig. 3 is a bottom edge view of a matrix havin molds for acombination of letters.

11 the drawings I have illustrated what I term a square matrix havingfour casting edges and each edge having two characters or combinationsof characters set reversely to each other. The reversed letter is at theright of the other letter and for distinction will be called the bottomletter. Ohter p0- lygonal forms of matrices may be used.

It so happens that in the use of four or more edged matrices with twoletters in each edge that one matrix will be used with a top letter andthe next with a bottom letter, and such letters may be found on the topedge or on the side edge, or on the bottom edge.

It is necessary to the best use of my matrices that each matrix shall onevery occasion occupy the same relative position in the magazine andshall be capable of being distributed by mechanism after the line iscast so as to enter the magazine with the same edge at the bottomthereof on every occasion of use and the same side or face always towardthe operator. To accomplish this result I have designed mechanism fordistributing the matrices to the magazine which will be described in anapplication hereafter to be filed. In order to render the matricessusceptible of such use the body 5 of each matrix is provides with akerf 6 in one edge near the top and a notch 7 at the top of the otheredge and a central transverse hole 8 which is preferably egg shaped.These central holes are so located that when the matrices are stackedtogether with the bottom edges on a level surface a line passing alongthe lower edge of each hole will be parallel with the surfaceon whichthey rest. These holes are further located so that when the matrix issuspended on a rod it will turn thereon to bring the bottom of thematrix directly below the rod, that is to say the hole is eccentric tothe magnitude or weight of the matrix. This construction is necessaryfor the proper distribution of the matrix by the mechanism designed byme for that purpose. Matrix impressions or molds 9 are provided in eachcasting edge and there are preferably two molds in each casting edge.When two are used they are set reversely to each other. i

' Having described my invention what I claim is: v t

1. A polygonal matrix having a central transverse hole, said hole beingeccentric to the Weight, said matrix having a plurality of castingedges, each casting edge having adifferent character.

2. A polygonal matrix having an egg shaped central transverse holetherein so located that the smaller end of the hole is nearest to thetop edge of the matrix and the bottom portion of the matrix is theheaviest,

said matrix having diiferent characters in each of its casting edges andeach edge forming a casting ed e.

3. A polygona matrix having a kerf in one edge near the top and a notchat the top of the other edge on the outer side thereof, said matrixhaving a central hole eccentric to its weight, and having a plurality ofcasting edges with different characters in each of said edges.

at. A polygonal matrix having a central transverse hole, the center ofmagnitude of which is eccentric to the center of gravity of the matrix,said matrix having a plurality of casting edges, each edge having adifferent character.

In witness that I claim the foregoing I have hereunto subscribed my namethis 1st
